The supermarket is also considering a shake-up of staffing arrangements at a further 59 of its supermarkets, the Guardian reports, with the possibility that staff could be asked to work in different departments if required.

Job losses are expected to be in the hundreds, according to the Guardian.

The redundancies come after Asda's accounts last week showed a fall in profits and revenue. Pre-tax profit fell by 19% to £791.7 million and sales dipped by 3% to £21.6 billion.

The UK's traditional "Big Four" supermarkets — Tesco, Sainsbury's, Asda, and Morrisons — are facing increased competition from German discounters Aldi and Lidl and from online players such as Ocado and Amazon.

Business Insider has contacted Asda for comment. The supermarket told the Guardian:

"We are currently in discussions with a number of our stores about changes that are needed to the number of hours required to run that store for our customers. It is common practice for a supermarket to need to make changes to hours based on the changing shopping habits of customers. We understand that any conversations about change are unsettling, but it is always our upmost priority to find alternative roles or working patterns for impacted colleagues."
